I thought I was going to lose my mind from all of the dings and chimes on my LC 200. I happened to stop by Gene Reed Toyota in North Charleston, SC today on the way back into town.
I went in and ended up finally getting them to hook a scan tool (i.e. laptop computer running windows Vista with software for Toyotas, Lexus, and Scions) up to my LC 200.
I actually watched the guy run through every single option on there with the software. He had never hooked up to an LC 200 before. In any event, I actually witnessed all the different screens.
It is very simple, they can simply use a stylus to click "on" or "off" for about every setting. I had them turn off both seat belt warnings, daytime running lights, various other chimes, and also customize certain settings (lowering delay time on headlight shutoff, lowering volume on the few chimes I left on there, etc.). There is no option even for the mechanic to disable any of the GPS / DVD safety features, at least that we could find.
Long story short - I feel like I got a new car all over again. It is very nice not to have to deal with the noise. Highly recommend it for anyone.
The bottom line - get the mechanic in the car and then he will let you change whatever you want. Don't ask the service desk about the seatbelt as they are gonna say "no."
Also - any Lexus dealer should be able to do it b/c its the exact same software.
